If throttling sound comes it may from bearings or non alignment of blower wheel. But in your unit I think, it's freon flowing.Some times it may happens from to non serviced unit for long time. Service your unit. Helpful?

Whine coming from the left front of engine. Sounds just like its low on power steering fluid but it is full. Could this be the water pump?


could be a water pump bearing ---idler puller pulley bearing---power steering pump bearing or gears --alternator bearings. Get a mechanic stethiscope from a auto spare shop and carefully place the tip on the housing of the units. If you hear a steady buzz then the bearing will be ok but if you hear a low grumble then that unit's bearings are on the way out.

Dryer won't start.. has power sounds like something binding. long buzzing sound when starter depressed. try once or twice and then nothing for a while. come back try again ..long buzzing sound again


Hi and welcome to FixYa, I am Kelly.

You did not include a make and model number for your dryer so... this is a GENERIC response. With a make and model number we can better help you.

The long buzzing your hearing is the motor winding trying to start the motor. After 30 - 45 seconds if the motor does not start the thermal overload will cycle and prevent further attempts for around 5 - 6 minutes until the motor winding cools down.

Causes of a dryer motor not starting:
1. Binding.
a. Broken dryer fan blade lodged inside the blower housing
b. Motor start switch failure
c. Motor bearing failure

2. Dryer drum bearing / roller problems
a. The drum can be bound up and dragging on internal components of the dryer
b. The Idler pulley bearing may have failed and it is now a brake.
c. Front or rear drum seals failed / pinched against rear or front of the chassis
d. Drum roller bearing failure and is now a brake.

Reach inside the drum and see if you can turn the drum. If you can not turn it with a little effort, you need to find out where the binding is inside your dryer.

This is the best I can do for the moment without a model number. With a Make and Model number I can provide parts listings and item numbers of where to check.

Thanks for choosing FixYa.

Sounds like a potentially bad motor. When trying to start the dryer, it may have opened the thermal protector, which is why you are no longer getting the noise. Check that nothing is just stuck in the drum seal or blower wheel, seizing the motor. If all is clear, replace the motor.

Fan motor is out or possibly the capacitor to the fan is bad. Would have capacitor replaced first then replace the motor if the capacitor didn't solve you problems.

Air Conditioner Compressor Fan Quit


Check the start capacitor. You may be able to see visual deformaty, otherwise, use a meter. The buzzing is most likely the contactors closing which uses a seperate 24v supply..

Compressor problem?


The buzzing is your compressor trying to start. It is going off on internal overload caused by heating up of the motor windings.If you have an amp meter you could check the amp draw of the comp against the locked rotor amps listed on the tag You could try to have someone test your run capacitor, which looks like a can. Could be round or oval with wires coming off it. Or try a hard start capacitor and relay to bust it loose if compressor rotor is stuck. If that doesn't do it the comp is bad.
